How can i use multiple SSL certificate with one IP:PORT on IIS 8

Question

I have 2 domains (www.domain1.com, www.domain2.com). For both, I have a separate certificate. Both domains have the same IP, but different host headers. How can I add https with cert1 to domain1 and https with cert2 to domain2 (on the same IP)? I tried to work around but didn't help me.

one www.domain1.com binding I have selected https then I have given the hostname as www.domain1.com then I have checked the SNI checkbox then I have selected the domain1 SSL.

Same steps I have done for www.domain2.com but when I run domain2.com it uses the SSL of domain1 since both domains have the same IP I don't know where I am missing my steps. You help will be much appreciated

Answer 1

As per my knowledge, For Multiple Certificates installation using SNI, You do not require to enter the host name and check the SNI checkbox for the primary domain (www.domain1.com), But it is compulsory to enter the host name and check the Require Server Name Indication box for second domain (www.domain2.com).

However, I recommend you to use Multi-Domain SSL certificate to protect multiple domains instead of using Multiple certificates.
